FIELD: removal of sediments from liquids. SUBSTANCE: proposed device includes vertical settling surface which is partially immersed in liquid and is made in form of cylindrical jacket consisting of fixed screen bars which are approximately half-round in shape and are located at definite distance; device is also provided with scraper rotatable around axis of settling surface; this scraper includes scraping members passing between screen bars and adjoining settling surface; transportation unit for discharge of sediment including tubular housing with intake opening and rotatable transportation screw feeder. Fixed half-round screen bars of settling surface are located towards direction of flow of liquid by their convex side, thus making sediment settle on the outside of the fixed settling surface. Scraping members of scraper pass between screen bars in opposite direction relative flow of liquid . Part of cylindrical jacket which is not occupied by screen bars is open. Transportation unit is mounted at inclined axis in chute. EFFECT: enhanced operational reliability. 10 cl, 9 dwg
